SHOCK-COMPRESSOR- SPECIFICATION forming part of Letters Patent No. 754,004, dated March 8, 1904.

Application filed February 10, 1903- Serial No. 142,766. (No model) I parts hereinafter described, and particularly I pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a front elevation of the device, showing the sleeve disengaged from the spool. Fig. 2 is a vertical section, taken on line am: of Fig. 1, with the lower part of the thrust-rod broken away. Fig.3 is a side elevation of the device with the thrustpinpartly broken away, showing the sleeve in engagement with the spool. Fig. 4 is a detail of the catch or dog for the guard -plate.-

Fig. 5 is a bottom view of the crank and cord carrier, and Fig. 6 is anisometric view of the guard-plate.

In the drawings, 2 represents a thrust-pin terminating at the top in a hollow shaft 3 and at the bottom preferably in a pointed end 4: to facilitate thrusting into the shock to be compressed. Upon the shaft 3 are secured collars 5 and 6, respectively, as best shown in Fig. 2, between which areloosely and revolubly mounted upon the shaft a guard-plate 7 and a spool 8, the spool being positioned above the guard-plate. The collars prevent longitudinal movement of spool and guard plate upon the shaft. The guard plate has upwardly-projecting slotted ends 9 and 10 to receive and guide the compressing-rope 11, one end of which is secured to an eye 12 upon one side of the spool 8 and the other end of which is formed with an eye 13, adapted to engage the hook 14: upon the other side of the spool.

The shaft 3 is turned by means of a crank 15, having at one end a handle 16 and at the other end a downwardly-projecting sleeve or clutch member 17, which fits loosely over the upper end of the shaft and is free to slide longitudinally thereon. To prevent the sleeve from being lifted entirely ofi the shaft and at the same time to allow it to slide freely thereon, the shaft is formed with a longitudinal slot 18, and apin or bolt 19 is passed through the sleeve and also through the slot 18. The lower end of the sleeve is formed with teeth 20, adapted to engage with the cooperating teeth 21 upon the upper end of the spool when the sleeve 'is slid down upon the shaft by the manipulation of the crank 15 or otherwise. By then turning the crank the spool is made to revolve with the crank and the shaft 3.,

winding up the compressing-rope from both ends simultaneously, as shown in Fig. 3. Pivotally supported between lugs 22 upon the under side of the crank or in any other suitable way and in a position to engage the upwardly-projecting guard ends is a dog or catch 23, (best shown in Figs. 3 and 4,) having a beveled lower end 24 and a heel 25 at the top. The catch is held normally in downwardlyextending position, with its heel thrown up against the crank by suitable spring means, such as the coil-spring 27. (Shown in the drawings.) When the crank is revolved and the beveled side of the catch strikes the upwardlyprojecting ends of the guard-plate, the catch will yield upon its pivot against the pressure of the spring and pass by the guard-plate ends,

the tops of which may be beveled to facilitate its passage. After passing the guard-plate end the catch will be thrown back by the spring until its heel comes against the crank and holds the catch from further backward movement. In this position the dog, catching against the projecting end of the guard-plate, will act as a stop to prevent the crank and spool from turning back to allow the rope to unwind.

Secured to the crank at its inner end, which may be provided with radial supporting-arms 28 for that purpose, is a box or carrier 29 for holding the binding-cord 30, as shown in Fig. 2. The cord passes through an opening 31 in the cover 32 of the box and thence through a guide 33 upon the side of the box and under a spring-strip 31 at or near the bottom of the box. The edge of the spring-strip is ground to a knife-edge, so that the cord may be cut by drawing it against the edge.

In use the lower end of the thrust-pin is thrust into the shock, and the rope 11, passing through the slot 35 in the projecting end 9 of the guard-plate, is carried around the shock and passed through the open slot 36 in the end 10 of the guard-plate, and the eye 13 at the free end of the rope is placed on the hook 14 upon the spool. The crank is pressed down to bring its sleeve 17 into clutching engagement with the spool and then revolved, thereby turning the spool to wind up the rope and compressing the shock with great force. The spool is held from turning back under the tension of the rope by the dog catching on the end of the guard-plate, which is in turn held by the rope passing through the slots in its ends. The binding-cord is then drawn from under the tension-spring, cut to the required length by drawing it against the knife-edge of the spring, and tied around the shock. The crank is then pulled out of engagement with the spool, and as the thrust-pin is withdrawn from the shock the spool turns back under the tension of the rope, which unwinds therefrom and slips off the hook.

I have made no claim to the twine-holding devices herein shown and described, for the reason that they have been claimed broadly in my application for Letters Patent filed December 29, 1903, Serial No. 186,955.

It is obvious that the details of the device may be variously modified without departing from the principle of the invention, the scope of which is defined in the claims.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, isp 1. A shock-compressor comprising, in combination, a thrust-pin, a spool carried thereby, a compressing-rope having its ends connected with the spool, and spool -engaging means also carried by the thrust-pin and adapted to be moved into engagement with the spool to cause the spool to revolve to Wind up the rope, and out of engagement with the spool to allow the rope to turn the spool and unwind therefrom.

with the spool to allow the rope to turn the spool and unwind therefrom.

3. A shock-compressor comprising, in combination, a thrust-pin, a spool loosely and revolubly mounted thereon, a compressin -rope having its ends connected with the spool, means carried by the thrust-pin for engaging the spool and causing it to revolve with the pin to wind up the rope, and means for preventing the pin and spool from turning back.

4. A shock-compressor comprising, in combination, a thrust-pin, a spool loosely and revolubly mounted thereon, a guard-plate also loosely and revolubly mounted thereon and having rope-guides at its ends, a compressingrope having its ends connected with the spool and intermediately engaging said guides, means to revolve the spool to wind said rope, and means to prevent the spool from turning back to unwind the rope.
